Emulator accuracy improvements

Today I ran multiple test ROMS through my emulator. It passed most of the quirks and flags tests. It had issues with they FX0A instruction though. My previous CPU handled this in a way that the code will stop execution forever, not good. So I fixed that(took way too long) and ran the tests again. I can now say I have made my own emulator!

Dev log #3

Today i finished a boot UI. from here you can choose a game rom and play it. You can also hit esc and return to the menu. I also included test roms just in case someone wants to test the emulator. Emulator doesnt pass some of the tests though so i gotta work on that =(

i made this lil guy, his name is greg

Got the emulator working

I finally got the emulator working. Here is a quick clip of me playing pong, forgive my nonexistent skills at pong

Dev log #1

This is a short project that I hope to finish in a few days…
Today I researched how the Chip-8 works, got some test ROMS, and wrote my CPU.
Next I hope to make a GUI that i can even export to web.
Im not sure what image to put here so here is js a pic of code

3128 added!

Only took like 3 redos =D
Has working intake, shooter, auto align. Not sure how climb worked, so I did not implement .t(didnt really see narwhals using it that much either)

Dev Log #2

Today I tried doing a web build, which did not turn out great. You could not see anything, so I fixed that by adjusting MSAA settings.
I am starting my first CAD robot. 3128(im doing the sd districts alliance)
intake lookin a bit goofy. Still needs a lot of work before it the robot is finished.
After this I plan to add 2102
Comment FRC team suggestions to see your robot added(cad would be rlly tuff)

Dev Log #1

Today i spent my time optimizing MoSimBuilder. Went from 9 fps -> 30 fps(my laptop kinda bad)

I also added my team’s robot. Comment your team number if you want your robot added…

Quick slicer update

I added a lil thing for you to be able to set a custom print speed. I also added integration and a fallback system to the printer.

guh

im so close to finishing this!

Slicer stuff

I refactored the slicer scripts and then made a cool tkinter GUI. You can move around your SVG(Sadly you cant print multiple at the same time).

Printer stuff

Using tkinter, I added a load button so you can load your .banana files way faster than using command line arguments.

Whats next?

• Better sprites for 2d printer app
• Get ready to ship(pls get me out of the depths of python)

more stardance logos!!! =D

GUI time!

I tried to fix my slicer issues, but that was a waste of time. I then fixed an issue present in the older versions of the slicer where the printer would begin extruding for infills before it reached the X Y coordinate of where it should start infilling. The slicer struggles to do really complex images howver, but I am okay with that because even being able to slice was a big challenge for me to complete.

Whats next?

• Basic GUI
  • Move around print
  • Allow user to load custom SVG’s

guh…

Bottom tier 2D printer moment

The slicer is absolutely NOT cooperating. I made two versions, each of which are better suited to different scenarios.

SlicerV2(left logo) Good when across the x axis, there are multiple points

SlicerV3(right logo) Good when there are multiple points along y axis.

They both are kinda bad, but I did optimize the slicer a bit. When from 35 elements/sec to around 25 elements/sec. Slicing still kinda takes a while though

send food pls, im hungry

Reorganized levels, added alarm clock to the second level. Now trying to come up with an idea for last level.

it made stardance logo(trust i should get an award for this)

This was a result of TONS of tuning(took like 50 min, but ig hackatime doesn’t support my slicer =p ) The printer needs some work on when to start and stop extruding.

im not gonna put a whats next here, i made like 3 devlogs today 😭

my 2d printer finally printed its first picture =D

slicer takes forever to slice it though, so I need to optimize it

Whats next?

• Slicer stuff
  - Faster and better
  - GUI

The intelligence of my slicer is now not 0

I took a lot of time rewriting the slicer’s infill methods, and now the slicer can print objects that aren’t squares. I also added padding so the image you print isn’t crammed into the corner

Whats next

• testing with more advanced svgs
• GUI slicer

My image slicer is finally working =o

I finally got the slicer to start giving me sliced files(only took like an hr =D )
The first image is the image i am supposed to get, but the next image is what i got lol. I still have a lot of stuff to do to get the slicer working better.

Whats next?

• add padding so that im not printing on the edge of the build plate
• fix the slicer infill issues
• add padding to slicer infill extrusions
• try actual SVG images
• GUI slicer:
  • Allow user to move around pieces on the build plate
  • Make settings like printspeed and stuff load from sliced files

SVG stuff =D
I finally made a basic SVG shape extractor. It uses the svgelements python library to get information about svg images.

The next step will be making a basic slicer, which will be able to use this information to “slice” the svg into a .banana file for the printer. Infill is gonna be annoying to implement though.

I finally decided to put this project on stardance. Currently, you can print simple drawings(very annoying to slice them). The printer works like this:

1. Sliced files:
   • Takes an argument from running to run a .banana file
   • Interpret and convert back into commands that the printer can understand
2. Renderer and movement
   • Python class stores x y info with a bunch of other stuff to send to renderer
   • Interpolation between points
3. Printing
   • Using pygame permanent canvas that doesn’t get erased when pygame.flip() is called.

Features as of now:

• Printing =0
• Toolhead path preview(“T” key)
• Make printhead slightly transparent(“shift” key, allows you to see the rest of the drawing if the printhead covers any part of it)
• Test path(runs path but doesn’t print and goes way faster)

Currently printing is pretty finished. The next goal will be making a slicer that slices scalable vector graphics(svg) into .banana files
